... CODEC ID Strapping Audio CODECs in the 48-pin package use pins 45 and 46 (defined as ID0# and ID1#) as strapping (i.e. configuration) pins to configure the CODEC ID. The ID0# and ID1# strapping bits adopt inverted polarity and default Primary (via a weak internal pullup) when left floating. This eliminates the need for external resistors for CODECs configured as Primary, and maintains backward compatibil- ity with existing layouts that treat pins 45 and 46 as “ ...
